+You need to create a database named **esp_data**. Then you can use this script to create a table:
+
+``CREATE TABLE 'temp_data' (
+  'id' int NOT NULL AUTO_INCREMENT,
+  'temp' float NOT NULL,
+  'time' timestamp NOT NULL,
+  'sensor_id' int NOT NULL,
+  PRIMARY KEY ('id')
+) ENGINE=InnoDB AUTO_INCREMENT=0 DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_0900_ai_ci;``
+
+or you can run ``setup.py`` file.
+
+
+### Esp8266
+To use this project you need an esp8266 with wifi support. You need only
+1. port D7, 3v, GND.
+2. a temperature sensor like 0750C3
+3. installed esp8266 plugin (fast [tutorial]( https://www.youtube.com/watch?v=OC9wYhv6juM&ab_channel=RuiSantos "tutorial"))
+4. know your wifi ssid and password
+
+#### Connecting esp8266 board
